Vitamin C for Hypertension
Ascorbate Versus Artery Damage
Vitamin C (also known as ascorbate) is another micronutrient that may lower our blood pressure. Like fish oil, the effect is small, but significant.
Vitamin C is a natural antioxidant that aids the body in fighting small, reactive molecules known as free radicals. These free radicals attack our tissues and are thought to be a key factor in the plaques that cause our arteries to narrow and harden,
The best way to get this powerful substance is to include a variety of fruits and vegetables in your diet. Capsicum, oranges, kiwifruit and brocolli are all good sources.
Ascorbic acid supplements are another alternative. If you're taking a supplement, 500 milligrams is enough to get the blood-pressure-lowering effect.ReferencesLinks
